  1. RadMon Radiation measurement results from CNGS side gallery Data from 2008 D. Kramer for the RadMon team

  2. Positioning of RadMons in the test area (naming conventions) Access door Rmon #6 Rmon #8 Rmon #7 #1 #4 #5 #2 Rmon #3 Courtesy of L. Sarchiapone D.Kramer TS-LEA

  3. TSG43 TSG42 Ventilation duct 10cm? Height 108cm 50cm Wall position 3LM06S TSG46 125cm Height 15 Floor position 3LM08S 60 Height 115 Wall position TSG45 49 60cm Floor position 3LM07S Height 10 25 Height 105cm (30 below PMI) Wall position RAMSES Positioning of RadMons in the test area Access door RMon #7 RMon #8 • Wall positions used before the installation of electronics • No electronics tests performed with RMon#6 • RMon#7 wall pos. comparable with PMI407 Access door RMon #6 D.Kramer TS-LEA-RAD

  4. RMon #8 for 7/10..3.11/08 floor positioni.e. from installation of equip. to end of beam Integrated beam intensity 6.43 1018 pot Transient effect caused by moving average D.Kramer TS-LEA

  5. RMon #8 for 7..23/10/08 floor positionfitted Hadron fluence vs. Beam intensity Integrated beam intensity 3.379 1018 pot D.Kramer TS-LEA-RAD

  6. RMon #7 working fine after position change, but… D.Kramer TS-LEA-RAD

  7. A power cut in the test station occurred after ~2h of beam D.Kramer TS-LEA-RAD

  8. RMon #7 power cut after ~2h of beam • 1st Beam after placement of electronics started • 10:45 on 9 Oct 2008 • Power off for Rmon#7 (caused by PConv rack) • 12:58 on 9 Oct 2008 • Integrated beam intensity = 2.01 1016 pot • Hadron fluence unavailable since due to HW problem D.Kramer TS-LEA-RAD

  9. RMon #7 power cut after ~2h of beam D.Kramer TS-LEA-RAD

  10. RMon #7 for 23/10..3/11/08 floor position Medium sensitivity Dose requires linearization Integrated beam intensity 3.047 1018 pot D.Kramer TS-LEA

  11. Combined results for the 5 RadMon positions normalized to 1018protons on target PRELIMINARY comparison with FLUKA data; High gradients, geometry details (corners, empty ducts) and statistics produce uncertainties of factor ~2 Generally higher Fluka values than measurements as seen with PMI comparisons (see talk of A.Ferrari in SBWG) D.Kramer TS-LEA-RAD

  12. Combined results for the 5 RadMon positions normalized to 1018protons on target D.Kramer TS-LEA-RAD

  13. RMon #3 for 7..29/10/08 ventilation room D.Kramer TS-LEA-RAD

  14. RadMon #3 location D.Kramer TS-LEA-RAD

  15. Values integrated by the RadMons in CNGS from 7 Oct 2008 (6.43 1018 pot) • Comparison with the values integrated during 1 year of Nominal LHC operation – alongside arc dipole • Dose : 10 Gy • Hadrons>20MeV : 4 1010 cm-2 • 1MeV eq. Neutrons : 3 1011 cm-2 D.Kramer TS-LEA

  16. TSG45 D.Kramer TS-LEA-RAD

  17. TSG46 D.Kramer TS-LEA-RAD
